IMPROVEMENT 1N cULTIvAToRs.

TO WIIOI I'I MAY CONCERN:

Be it known that LENOCU. E. STUBBS. of West Elkton, in Preble county, in the State 0f 0hio,have invented certain new and usei'ul Improvements'in Cnltiv'ators; and I do hereby declare that the following is a full and exact description thereof, reference being had tothe accompanying dravinggand to the'letters of reference marked thereon. i

Figure 1 represents aside viewof my improved cultivator.

Figure 2 represents a plnn or top view of the same.

Figure 3 is the clearing-hoard of the harrow-box;l and `Figure 4 is a sectional view of -the barrow and its guide-box.

My invention consists in the combination of av roller, a'hurrow; and cutters, with, mechanism for raising and lowering the t`\vo latter, arranged in a rectangular'frame, as will be herein fully described.

A A'represen*l the wheels supporting the frame B C, in which the piroted frames e c and 6b are placed. The frame e e hns n series of'knives, d, connectedlv with its rear cross-piece, and the frame I) b carriesthe roller D. lThe rear-crossieee C of the main frame isin theforui of e. box.in which the barrow E ,is retained. as re re- P P sented in fig. 4. The bottom portion of the barrow-box is perforated for the harrow-teeth, as seen in fig. 3. Two studs, ff', project upwards from the cent1-ul portion ofthe cross-tiles of the main iframe, and the leversgh are piv- .otedrespectivcly to the stndsff. These levers are nlsopivoted to shoi'tstuds connected with the barrow-E and knife-frame e e, and levers gnnd L are also connected together at theirfront ends by the link z', as represented in fig. I. 'lhe drivers scat n is supported upon tivo nprights, o, fastened to the side'p'ieces B of the main frame. The frame b b of the roller D is pivoted to theinner ends of the axle-pins a of the wheels A A, and the knife-frame e e is pivoted to the inner sides of the frame pieces Bfns indicated in dotted lines in tig. 1.' The tongue-n may -be connectedv by vhinge fastenings to the main frame, or it may be inserted in a. mortise in the front cross-piece C, at any desired angle tothe mitin frame necessary to the proper working of the parts.4

When the machine is in use, and as itprogresses, the knives d, roller D, and harrowE rest upon the ground upon which the wheels A A revolve to carry the machine. The knives 0l c ut and separate the soil over' which roller D passes to breakV up the clods, and finally theharrow penetrates the soil and mellows it in a. superior manner. Whenever the hul-row becomes foul with'rwe'eds orV other mn-tterhy means loi' the lever g the driver may raise it., drawing its teeth through the holes in the bottom bonrdof barrow-'box @,iand eectually clearits teeth frouiall obstructions. At the 4sometime that the barrow is elevated,l the knife-frame e e, with its knives, will be rnised np to permitnny obstructing matter to becomevletached therefrom.` l

Another convenience and advantage of my improved cultivator is in this capability of raising the knives zindiharrows to pass from field to Held, and to pass over obstructions when in use. And when it is necessary to retain the harrow and the knives in an elevated position' the hinged levers may be moved sideways bythe attendant so as to bring its notch t over the lever g, in front of ,the seat n, which' will retain the harrow and knives with the knife-frame e e above and ont of contact with'obstrnctions over which the machine may progress.

Having now` fully described my invention, what I claim, -and desire to secure by Letters Patent, is-` The combination of the knives d, roller D, and barrow E, with the levers g,'t,v and perforated harrowbox," and main frame, the parts being arranged, connected, :ind operating together `in the manner and for the purpose specified. l

In testimony whereof Ihavehereunto set my hand this 22d day of May, 1867.
